Many novel interfascial plane blocks have been developed in the last 10 years in the effort to improve perioperative pain management that are safe, efficacious, efficient, and inexpensive. These blocks have been widely adopted into clinical practice despite relatively few high-quality clinical investigations of the techniques and how they affect perioperative outcomes. This article defines interfascial plane blocks, discusses the potential benefits, reviews the most common techniques and evidence supporting their indication, and guides clinicians in selecting an appropriate interfascial plane block for different types of surgical procedures.

Review Meta Analysis Comparative Study
Comparison of adductor canal block with local infiltration analgesia in primary total knee arthroplasty: A meta-analysis of randomized controlled trials.
Currently, there remains a paucity of literature about the efficiency of adductor canal block (ACB) versus local infiltration analgesia (LIA) for pain management after total knee arthroplasty (TKA). The purpose of this study was to perform a relatively credible and overall assessment to compare the efficiency of ACB versus LIA for early postoperative pain treatment after TKA. ⋯ Both treatments provide similar overall pain relief after TKA. LIA may achieve earlier ambulation compared with ACB. More high-quality RCTs are still required to make the final conclusion.

The optimal order of drug administration (sedative first vs. neuromuscular blocking agent first) in rapid sequence intubation (RSI) is debated. ⋯ Administration of either the neuromuscular blocking or the sedative agent first are both acceptable. Administering the neuromuscular blocking agent first may result in modestly faster time to intubation. For now, it is reasonable for physicians to continue performing RSI in the way they are most comfortable with. If future research determines that the order of medication administration is not associated with awareness of neuromuscular blockade, administration of the neuromuscular blocking agent first may be a logical default administration method to attempt to minimize apnea time during intubation.

Randomized Controlled Trial
Continuous femoral nerve block is more effective than continuous adductor canal block for treating pain after total knee arthroplasty: A randomized, double-blind, controlled trial.
Previous studies comparing adductor canal block (ACB) with femoral nerve block (FNB) are inconclusive with regard to patient-controlled analgesia (PCA) induced by opioids. Moreover, some postoperative pain severity results differ between previous randomized controlled trials (RCTs). The primary aim of the current study was to compare total intravenous morphine consumption administered via PCA during the first postoperative day in continuous FNB and ACB groups after total knee arthroplasty (TKA). Secondary aims included evaluation of postoperative pain via a visual analog scale, degree of knee extension, quadriceps muscle strength, and ability to sit, stand upright, and walk. ⋯ FNB was associated with the perception of less severe pain after TKAs. However, ACB was associated with earlier mobility rehabilitation.

ReviewInjection pressures measuring for a safe peripheral nerve block.
The performance of a precise and safe peripheral nerve blockade (PNB) can currently rely on the aid of the ultrasounds and nerve stimulators. The injection pressure monitoring may be beneficial to perform a safer procedure. This review focuses on the pressures measured during PNB among studies conducted on animal, and human models. ⋯ So it is desirable to make further studies in order to assess them. In the future, the monitoring of the pressure could allow the use of a minimal quantity of anesthetic, empowering the safety of the nerve blocks. Moreover, the sensitive system should not be invasive and it should not hinder the job of the anesthetists.
